This module outputs various kinds of lists. At present, it supports bulleted lists, unbulleted lists, horizontal lists, ordered lists (numbered or alphabetical), and horizontal ordered lists. It allows for easy css styling of the list or of the individual list items.

Parameters

Positional parameters (1, 2, 3...) - these are the list items. If no list items are present, the module will output nothing.

start - sets the start item for ordered lists. This can be a start number for numbered lists, or a start letter for alphabetical lists. Horizontal ordered lists only support numbers.

type - the type of marker used in ordered lists. Possible values are "1" for numbers (the default), "A" for uppercase letters, "a" for lowercase letters, "I" for uppercase Roman numerals, and "i" for lowercase Roman numerals. Not supported in horizontal ordered lists. See also the list_style_type parameter.

list_style_type - the type of marker used in ordered lists. This uses CSS styling, and has more types available than the type parameter, which uses an html attribute. Possible values are listed at W3schools' list-style-type page. Support may vary by browser. list-style-type is an alias for this parameter.

list_style - a custom css style for the list itself. The format is the same as for the |style= parameter.

item_style - a custom css style for all of the list items (the <li>...</li> tags). The format is the same as for the |style= parameter.

item1_style, item2_style, item3_style... - custom css styles for each of the list items. The format is the same as for the |style= parameter.

item1_value, item2_value, item3_value... - custom value for the given list item. List items following the one given will increment from the specified value. The value should be a positive integer. (Note that this option only has an effect on ordered lists.)

indent - this parameter indents the list, for horizontal and horizontal ordered lists only. The value must be a number, e.g. 2. The indent is calculated in em, and is 1.6 times the value specified. If no indent is specified, the default is zero.
